However here are some reminders: The Portico 5024 dissipates about 15 watts, which means that it will get warm in use. The heat generated is radiated through the case work. To avoid overheating Portico™ modules should not be stacked imme- diately above or adjacent to other equipment that gets hot. - Page 3 Portico 5024: Block Diagram...

MICROPHONE PREAMPLIFIER DESIGN NOTES In former years, before the introduction of solid state amplifiers, transformers were necessary to step up to the very high input impedance of tubes, and to provide a balanced input for the microphone line. An input impedance of 1,000 or 1,200 ohms became established for microphones having a source impedance of 150 or 200 ohms, with connection being made on a twisted twin screened cable (This type of cable, while excellent for low impedance work, has high capacitance between its conductors and between each conductor and screen. - Page 5 The Portico 5024 microphone amplifier provides an input impedance of 10,000 ohms which means that variations in microphone source impedance with frequency, have only a very small effect on the sonic quality.

When the Mic Gain switch is set to Unity (0 dB), the Portico 5024 microphone pre-amplifier can handle a balanced input signal of more than +20 dBu without an input attenuator pad! This is a unique feature that enables this input to double as an additional line input. - Page 9 5024 is connected.
